Journal ArticleDOI
Interfacial tension between low pressure argon plasma and molten copper and iron
P. Sahoo,Tarasankar Debroy +1 more
TL;DR: In this paper, the interfacial tension between the molten metal and the surrounding plasma environment was measured and the variables studied were temperature and the intensity of plasma emission, and the effect of plasma on the interfacer tension of molten metals is not known.
Journal ArticleDOI
Three-dimensional Monte Carlo simulation of grain growth in zone-refined iron
S. Sista,Tarasankar Debroy +1 more
TL;DR: In this article, the evolution of the grain structure and topological class distributions in zone-refined iron were modeled using a 3-dimensional (3-D) Monte Carlo (MC) model.
Journal ArticleDOI
Enhanced dissolution of nitrogen during gas tungsten arc welding of steels
Todd Palmer,Tarasankar Debroy +1 more
TL;DR: In this article, a comprehensive analysis of the nitrogen containing plasma phase of a gas tungsten welding arc is presented, showing that ionised species dominate close to the electrode, whereas neutral monatomic and diatomic nitrogen are the primary species near the metal surface at plasma temperatures as low as 5000 K.
Journal ArticleDOI
Asymmetry in steel welds with dissimilar amounts of sulfur
TL;DR: In this paper, it was shown that the reported arc shift is a consequence of asymmetric melting rather than its cause, and that Marangoni convection causes these rotational and translational asymmetries.
Journal ArticleDOI
Neural network model of heat and fluid flow in gas metal arc fillet welding based on genetic algorithm and conjugate gradient optimisation
Amit Kumar,Tarasankar Debroy +1 more
TL;DR: In this paper, seven feed-forward neural networks were developed for gas metal arc (GMA) fillet welding, one each for predicting penetration, leg length, throat, weld pool length, cooling time between 800uC and 500uC, maximum velocity and peak temperature in the weld pool.
